Extron Electronics FOX Matrix 7200 - Manual (Page 13)

Operational reliability — The FOX matrix switcher can support round‑the‑clock operation
in mission‑critical applications, using a combination of hot‑swappable components and
redundant power supplies.
• Field upgradable, hot-swappable modular design — You can repair, upgrade,
reconfigure, or expand the matrix by simply installing a new I/O board or replacing a
board of one type with one of another. Hot‑swappable components let you replace any
I/O board at any time without powering down the switcher.
• Power redundancy — The built‑in redundancy ensures zero downtime and no loss of
functionality through all but catastrophic power failure.
• Two AC power inputs — The switcher can remain powered through any power
interruption short of a simultaneous loss of power on both power sources.
• Primary and redundant, hot-swappable power supplies — The hot‑
swappable, externally mounted redundant power supply is configured to
automatically take over the load from the primary supply in the case of a failure.
The complete power circuit, from the plug, through the power supply, to the
insertion of the power onto the power distribution plane, is separate and redundant
(see figure 2). If the installation includes uninterruptible or completely separate
power sources, the switcher remains powered up through any power interruption
except a simultaneous loss of power on both power sources.

The hot‑swappable redundant power supply means no downtime for the switcher
and no loss of functionality should one power supply fail. Should a primary power
supply fail, the redundant power supply immediately assumes the load of the failed
primary supply. A failed power supply is easily replaceable from the rear at any time
without powering down the matrix and with no tools required.
• Ease of maintenance — A failed power supply can be easily replaceable from the
rear at any time without powering down the matrix, and with no tools required.
• Power supply status LEDs — Front panel and rear panel LEDs indicate the status
of the primary and redundant power supplies.
• Hot-swappable fans — The hot‑swappable, externally mounted fans allow quick
replacement to avert overheating in the case of a failure. Fans can be replaced
without powering down the switcher.
• Operational flexibility — Operations such as input/output selection and setting of
presets can be performed using a variety of local and remote control mechanisms:
• Front panel controller
• Windows‑based Matrix Switchers Control Program
• Simple Instruction Set (SIS)
• Remote control panels and keypads
